Abstract

Computed tomography is replacing contrast radiography as the method of choice in evaluating congenital posterior choanal atresia. Careful preparation of the patient, however, is necessary prior to the examination in order to obtain the maximum of information pre-operatively.

We present patients with inadequate preparation and illustrate their misleading scans. The proper method of examination is discussed, with a review of the literature; it is essential to remove nasal secretions by suction and instil vasoconstrictor nose drops, shortly before scanning.
